A new study in the journal Pediatrics has found that women who had the flu or prolonged fever during pregnancy were twice as likely to have an autistic child than those who did not.
The researchers involved in the study wrote: “We found almost a twofold increased risk of infantile autism in the child after self-reported infection with influenza virus during pregnancy,” which suggests that the mother’s immune response may affect a child’s developing brain. However, women who reported other infections during pregnancy, such as a cold or UTI, were not any more likely to have a child with autism. Health officials said the finding reinforces their recommendations that pregnant women should get flu shots, which will protect the mother and baby for the first six months after birth.
Additionally, researchers found that women who had a fever lasting a week or longer—either caused by the flu or unrelated to the flu—were three times as likely to give birth to a child with autism, which supports findings from a recent study published in the Journal of Autism and Developmental Disorders.
“It is important to bear in mind that when you look at the absolute numbers, we see that around 99 percent of women reporting to have had influenza or fever during pregnancy, do not have children with ASD (autism spectrum disorder),” researcher Dr. Hjördis Ósk Atladóttir of the University of Aarhus in Denmark told NBC. “We want to reassure women. In this study, most women who experienced flu or prolonged fever or who were taking antibiotics did not have children with an autism spectrum disorder,” asserted Boyle.

A new study published in the Journal of Autism and Developmental Disorders has found that women who have fevers while they are pregnant have a higher risk of having a baby with an autism spectrum disorder. From The New York Times:
In the new analysis, researchers studied 701 children with autism spectrum disorders or developmental delays and 421 normal controls. After adjusting for age and other health and socioeconomic variables, they found that women who reported having had a fever during pregnancy were more than twice as likely as those who did not to have a child with a developmental disorder.
Among women whose fever had been treated with drugs like Tylenol or Advil, the risk was indistinguishable from that of mothers who reported no fever.
“Fever is an acute inflammatory response,” said the senior author, Irva Hertz-Picciotto, a professor of environmental epidemiology at the Mind Institute of the University of California, Davis. “So there is a suggestion that inflammation of some sort may play some role in autism causation. Untreated fever seems to be the place where the risk is.”

Health officials say four children were infected with a new strain of swine flu, MSNBC.com reports.
All four children, three girls and one boy, have recovered or are recovering, and were infected through contact with pigs. The virus does not appear to spread easily from person to person, experts at the Centers for Disease Control and Prevention say.
MSNBC.com gave these details about symptoms in two of the children:
In July, the boy was taken to a hospital emergency department with flulike symptoms of fever, cough and diarrhea, where a respiratory test confirmed influenza A (H3). The boy, who has multiple chronic health conditions, was briefly hospitalized. He had not been directly exposed to swine but a caretaker had been in direct contact with swine in the weeks before the boy became ill.
In August, [one of the girls] was also taken to a hospital emergency department with similar symptoms and discharged. A few days before she became sick with a fever, cough and lethargy, she reportedly visited an agricultural fair where she was exposed to swine.
This brand-new flu strain picked up a gene from the H1N1 strain that set off the flu pandemic in 2009 and 2010. Gene sharing among flu viruses is common, and causes problems when it creates novel strains to which people lack immunity, The Washington Post explained.
The new swine flu is unlikely to trigger a pandemic the way H1N1 did, experts say. CDC spokesman Tom Skinner told MSNBC.com, “There’s no evidence of sustained transmission from human to human.”
MSNBC also reported that in the first two cases, both children received flu vaccines in September 2010, which protected them against H1N1, but wouldn’t protect against the new virus.
